What I meant is that cancer is far more than just one thing to cure. I have a friend who's a cancer researcher working with immunotherapy, one of the more promising new directions for cancer research. And yet, even if we can cure, say, leukemia with it, there's still other cancers that may or may not be curable in the same way.
Still, it is a hope that one day we'll have a cure for all the varied types of cancer. It's still not going to be easy.
